the prose in which they are imbedded by certain peculiarities of their own and by a more archaic character. Allied to these is a remarkable poem of this period, the Suparṇādhyāya, an attempt, after the age of living Vedic poetry had come to an end, to compose in the style of the Vedic hymns. It contains many Vedic forms, and is accented, but it betrays its true character not only by its many modern forms, but by numerous monstrosities due to unsuccessful imitation of the Vedic language.
A further development are the Āraṇyakas or "Forest Treatises," the later age of which is indicated both by the position they occupy at the end of the Brāhmaṇas and by their theosophical character. These works are generally represented as meant for the use of pious men who have retired to the forest and no longer perform sacrifices. According to the view of Professor Oldenberg, they are, however, rather treatises which, owing to the superior mystic sanctity of their contents, were intended to be communicated to the pupil by his teacher in the solitude of the forest instead of in the village.
In tone and content the Āraṇyakas form a transition to the Upanishads, which are either imbedded in them, or more usually form their concluding portion. The word upa-ni-shad (literally "sitting down beside") having first doubtless meant "confidential session," came to signify "secret or esoteric doctrine," because these works were taught to select pupils (probably towards the end of their apprenticeship) in lectures from which the wider circle was excluded. Being entirely devoted to theological and philosophical speculations on the nature of things, the Upanishads mark the last stage of development in the Brāhmaṇa literature. As they generally come at the end of the Brāhmaṇas, they are also called Vedānta
